SCRAPER ATTAC HMENT'FOR COTTON-CHOPPERS.

SPECIFICATION forming part of Letters IPatent No. 694,475, dated March 4, 1902.

Original application filed December 14, 1899, Serial No. 740,228. Divided and this application filed January 24, 1901. Serial No. 44,532 (No model-l .To aZZ whom) it may concern:

Be it known that I, AARQNL. HOOKETT, a

citizen of the United States, residing at Mastodon, in the county of Panola and State of Mississippi, have invented certain new and useful Improvements in Ootton- Choppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel scraper attachment for cotton-choppers, and more particularly to the means for mounting the scraper-wheels in a manner toinsure their effective operation.

The object of the invention is to so mount the scraper-wheels that while their proper relative positions will be maintained their relative adjustment may be readily effected and their yielding to prevent breakage or derangement when opposed by a stone, root, or other obstruction will be insured.

A further object of the invention is to provide simple and effective means for raising or lowering the wheels at the will of the operafor out of or into their operative positions.-

To the accomplishment of these ends the in- Vention consists in the peculiarities of structure and arrangement hereinafter described and illustrated, and succinctly pointed out in the appended claims.

Referring to the drawings, Figure l is a plan View of a cotton-chopper equipped with my scraper attachment. Fig. 2 is a front elevation thereof. Fig. 3 is a sectional view of a portion of the chopper, showing the attachment in elevation. Fig. 4 is a detail sectional View of the scraper-lever, and Fig. 5 is a detail rear elevation of the scraper-wheels and their mounting.

Referring to the numerals of reference, indicating corresponding parts in the several views, 1 indicates the supporting-axle of a cotton-chopper carried by wheels 2 and carrying a rearwardly-extending angularly-disposed frame 3, constituting a support for the shaft at of the chopper-wheel 5, the choppershaft at being geared to the axle, as by miter gear-wheels 6 and 7.

The main frame or yoke 8 of the machine projects forwardly from the axle, as usual, be-

ing supported therebyin anyIdesired manner, and constitutes a support for the spring-seat frame 9, designed for the accommodation of the operator. This assemblage of parts is described for the sole purpose of making clear the application of my attachment and forms no part of my present invention except in so far as it may constitute a vehicle for its effective utilization.

Proceeding now with the description of that portion of the illustrated structure whereinmy present invention resides, ,10 designates aframe suspended from the axle l by means of abearing 11, through which the axle passes, and held against lateral play by the collars 12 and 13, carried by the axle. This frame 10 is provided with parallel perforated ears let and 15, within which is guided a verticallyadjustable plunger-bar 16, formed with a shoulder 17 and surrounded at its upper portion by a coil-spring 18, which bears against the ear 14 at one end and the shoulder 17 at its opposite end. At the lower end of the bar 16 are located two diverging arms 22, each of which is formed with a series of holes 23 to receive a spindle 24 of a scraper-wheel 25. The two wheels 25, as shown, rest at an angle to each other and are adapted to operate on opposite sides of a row of cotton. The holes in the arms 22 permit the scraper-wheels to be adjusted toward or from each other.

At the bent or angle point of the-bar 21 is attached one end of a cord or chain 26, the opposite end of which passes around and is secured to a cam 27, provided with a lever 28. The cam is pivoted between ears 29, projecting from a bracket 30, secured to the center of the yoke 8, and the cam is recessed to receive a spring-pressed slide 31, connected by a Wire 32 with a finger-piece 33, fulcrumed in the handle of the lever 28. By throwing the lever 28 rearward .to the position shown in dotted lines in Fig. 3 the scraper-wheels are elevated out of working position and are locked in this position by the engagement of the end of the slide 31 with the center of the bracket 30.

The operation of the machine will be readily understood. The inclined oppositely-disposed wheels 25 scrape the earth and shape the row ahead of the chopper, which thins the cotton into bills, as is well understood in this art. It maybe mentioned in conclusion, however, that by means of this construction and arrangement the scraper-wheels may be adjusted toward or from each other without disturbing their angular relation and may be quickly raised out of their operative positions, the pivotal mounting or suspension of the frame preventing derangement when turning or backing and the yielding mounting of the plunger-rod serving to insure efiective operation of the wheels.

The subject-matter of this application is divided out from the applicants other case, No. 710,278, filed December 14, 1899.

\Vhat I claim is- 1. In combination, a supporting-wheel, an axle extending between the same, a yoke secured to and projecting forwardly from said axle, scraping-disks, a frame carrying the same depending from said axle, and means having a connection to the frame for tilting the latter supported upon said yoke.

2. In combination, a supporting-wheel, an axle extending between the same, a yoke secured to and projecting forwardly from said axle, scraping-disks, a frame carrying the same depending from said axle, a cam supported to have turning movement on said yoke, means for rotating the cam, and a flexible connection between the latter and said frame.

3. The combination with the supportingwheels and axle of a frame journaled on said axle, a pair of scraping-disks, means at the lower end of said frame for engaging and permitting the relative adjustment of the disks, and means for tilting said frame, substantially as shown and described.

4. The combination with an axle and wheels,of a scraper-frame pivotally carried-by the axle, a lever operatively connected with the frame,scraper-wheels and a spring-pressed plunger-bar supporting the scraper-wheels, and carried by the frame.

5. The combination with an axle and wheels, of a frame suspended from the axle, a springpressed plunger-bar carried by the frame, divergent arms at the lower end of the bar, and a scraper-wheel adj ustably carried by each arm.

6. The combination with the machine-axle, of a frame suspended therefrom, and provided with perforated ears, a spring-pressed plunger-bar supported by said ears, diverging arms at the lower end of said bar, scraperwheels adj ustably secured to said arms, and means for raising the scraper-wheels comprising a cam-lever 0n the frame, and a flexible connection between the cam-lever and the wheel-supporting devices.

In testimony whereof I aifix my signature in presence of two witnesses.
